Precision Metal Injection Molding Solutions
Advanced manufacturing technology combining the design flexibility of plastic injection molding with the strength and durability of metals.
What is Metal Injection Molding?
Metal Injection Molding (MIM) is a precision manufacturing process that combines the versatility of plastic injection molding with the mechanical properties of metals. This innovative technique allows for the production of complex, high-precision metal components with excellent surface finish and tight tolerances.
High Precision
MIM technology enables the production of intricate geometries and complex shapes that are challenging or impossible to achieve with traditional manufacturing methods.
Cost-Effective
For small to medium-sized components produced in high volumes, MIM offers significant cost advantages over machining, investment casting, and other manufacturing processes.
Material Versatility
MIM supports a wide range of materials including stainless steels, low alloy steels, tool steels, titanium, and superalloys, providing excellent mechanical properties.
The Metal Injection Molding Process
The MIM process combines the design flexibility of injection molding with the material properties of metals, enabling the production of complex components with high precision and efficiency.
Feedstock Preparation
Metal powders are mixed with a binder system to create a homogeneous feedstock with suitable flow properties for injection molding.
Injection Molding
The feedstock is injected into a mold cavity under high pressure, forming the desired shape. The process is similar to plastic injection molding but uses metal-based feedstock.
Debinding
The binder is removed from the molded part through thermal or chemical processes, leaving a porous metal structure that retains the shape of the original component.
Sintering
The debound part is sintered at high temperatures, causing the metal particles to bond together and densify. This results in a component with near-full density and excellent mechanical properties.
Finishing
Optional secondary operations such as machining, heat treatment, surface finishing, or plating may be performed to achieve specific requirements.
